[Rust] Add support for `--seed`

[bugarela]

This involves:

• Checking for the seed param and setting the random generator state if it is present
• Saving the seed for each stored trace

Hello @bugarela, Can I work on this?

[bugarela]

@ginzahatemi yes! Just to make it clear, this is on the rust evaluator, as the typescript version already has it.
